Personally I have yet to partner on a deal. It seems there are probably a few different ways to do it, and it would be best to find one that suits your situation best.
This being said, I hear a lot of times people forming an LLC or an entity of some kind. Agreements are drawn up outlining what each person is responsible for and how funds will be used. Basically think of anything & everything that might be questioned later on and think about these now. This could include:
- How will the funds be used?
- What happens if someone backs out?
- If more funds need to be used, how will this work?
- etc.
Next, each party would insert funds into the LLC or entity. The entity then acquires investments and distributes profits/cashflow based on the original agreement.
One thing that I keep hearing over and over from others that are a part of an investment group, is make sure things are in writing. This way you have a document to refer to just in case things don't turn out as expected. Best of luck to you!
